Phys.org / Antarctic waters DNA survey discovers many microbial genes new to science
The Southern Ocean—vast, boundless waters surrounding Antarctica—plays an outsized role in global climate, largely thanks to tiny drifting organisms called plankton that soak up carbon. Reporting in Nature Communications ...
Phys.org / Ancient stone jars shows how tree cover shapes freshwater ecosystems over millennia
Researchers at McGill University used 2,000-year-old stone jars in Laos to observe long-term ecological processes, enhancing understanding of how strongly tree cover shapes small freshwater ecosystems. Their findings stand ...
Phys.org / Chemical shifts help track molecules breaking apart in real time
When molecules fall apart, their electric charge doesn't stay put—it rearranges as bonds stretch and break. An international team of scientists has now tracked these ultrafast changes in the small molecule fluoromethane ...
Medical Xpress / Why anger feels close to fear: Brain charts emotion in a map-like way
It is well established in psychology that humans conceptualize emotions by features known as valence (the degree of pleasantness or unpleasantness) and arousal (the intensity of bodily reactions, such as rapid breathing or ...
Phys.org / Hybrid synthetic strategy unlocks previously unattainable molecular architectures
The molecular-scale design of materials is one of the major frontiers in modern science. Flat, highly conjugated organic molecules are already used in advanced technologies such as chemical sensors, optoelectronic devices, ...
Tech Xplore / Can AI read papers like a scientist? A new benchmark shows where LLMs fail
To stay up to date and work forward in their fields, scientists must have at their fingertips and in their minds thousands of published studies. Large language models (LLMs) show promise as a tool for exploring the vast scientific ...
Phys.org / Scientists document Europe's first Jurassic lizard trackways in Asturias
The article presenting the research results was published online at the end of February in the journal Ichnos. The study focuses on two trackways (T1 and T2) preserved as convex hyporeliefs on the underside of a Late Jurassic ...
Phys.org / Gnaw-y by nature: Researchers discover neural circuit that rewards gnawing behavior in rodents
Researchers at the University of Michigan have discovered that the constant gnawing of rodents isn't just a reflex or a consequence of a tough diet. It also triggers a release of dopamine in the brain—which acts as a biochemical ...
Phys.org / Miniature laser technology could bring lab testing into your home
A research team at Chalmers University of Technology, Sweden, has developed new laser technology that could lead to tiny, cost-effective biosensors. The sensors integrate lasers and optics together on a centimeter-sized chip, ...
Tech Xplore / The AI that taught itself: How AI can learn what it never knew
For years, the guiding assumption of artificial intelligence has been simple: an AI is only as good as the data it has seen. Feed it more, train it longer, and it performs better. Feed it less, and it stumbles. A new study ...
Medical Xpress / IVF not linked to higher overall cancer rates, but study shows differences in some cancers
Women who used fertility treatments had no higher overall risk of invasive cancer than other women, a large Australian study led by researchers from UNSW Sydney has found. The study, published in JAMA Network Open, analyzed ...
Phys.org / A new model defines an upper limit to planetary radiation belt intensity
We all know that stars radiate light and much more. But radiation belts can also surround many other celestial bodies, such as planets. These belts do not generate particles themselves—the belts receive them from nearby ...
